New proprietary advanced pet formula includes ingredients that penetrate deep into the carpet fiber and eliminate the most stubborn pet stains and odors like pet urine and deter re-soiling. BEFORE CLEANING: Test a small hidden area of carpet for colorfastness. If color changes, do not use. For upholstery, read manufacturer's cleaning tag. Use only on items coded "WS" or "W". DIRECTIONS: Vacuum carpet. For best results, pre-treat tough stains. Shake contents well. Add 3 ounces per gallon to warm water in the clean water tank. For AutoMix machines, fill solution tank. Always consult owner's manual. Vacuum once your carpet has dried.
